Finish any previous activity in stack from current activity?

Question

How to finish any previous activity in application stack (at any level , I mean not immediate parent) , from current activity like on some particular event I want to invalid

Answer 1

I know this answer may be late, but I'm still going to post it in case someone is looking for something like this.

What I did is I declared a static handler in in ACTIVITY_A

public static Handler h;

and in my onCreate() method for ACTIVITY_A, I have

h = new Handler() {

        public void handleMessage(Message msg) {
            super.handleMessage(msg);

            switch(msg.what) {

            case 0:
                finish();
                break;

            }
        }

    };

Now, from any activity after this one, such asACTIVITY_B, or ACTIVITY_C I can call

ACTIVITY_A.h.sendEmptyMessage(0);

which then calls finish() in ACTIVITY_A and ta-da! ACTIVITY_A is finished from a different activity.
